.WATER-DISTILLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 505,641, dated September 26, 1893.

Application filed April 4, 13193.

To all whom it may concern:

Be it known that 1, WILLIAM ROGHLITZ, a citizen of the United States, residing at Ohicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Distilling Apparatus, of which the following is a specification. V

The drawing is a vertical central sectional View of a water distilling furnace employing my improvements and more especiallyadapted for laboratory use; certain parts of the structure being in elevation with portions broken away to expose details which would otherwise be hidden.

A is adrum,.aifordinga chamber A, mounted upon legs t and provided near its upper edge with a series of openings 3.

B is a bowl-shaped receptacle provided with a circumferential rim r, at which it rests upon the upper edge of the drum A. The body portion r of the receptacle 13 extends downward into the drum out of contact with the latter, as shown, to leavea free annular passage, from the lower part of the chamber A around the body of the receptacle to the openings s. Fitting a socket around the upper edge of the rim r is a preferably rubber gasket r 0 is a cover for the receptacle B, formed with an annular chamber or compartment O, a chamber or compartment 19, and a basin 0. The cover rests near its circumference upon the gasket 0. That portion of the cover affording the compartments q, p, is of conical shape, and the compartment q is'around an opening 10' which extends from the receptacle B to the compartment 19. On the cover 0 is a ring n, concentric with the rim of the basin 0, and provided around it close to the cover with a series of openings n. Fitting upon the ring 72 is a drum m affording a circular chamber m. Extending to the chamber m, at one side and about midway of its height, is a water supply pipe m Mounted upon the chamber m is a circular chamber Z, having the base Z and top Z the top Z is an opening Z Extending from the chamber Z down one side of the device is a pipe 70, to the lower end of which is swivcled a pipe the pipes being held together at a bracket 8' on the side of the drum A. The

At the center of Serial No. 468,992. (No model.)

. pipe 70' is bent to the form shown, and is provided near its end with an internal nozzle k surrounded by perforations 70 in the pipe. Around the perforations k is a chamber 764, on the pipe, which communicates through a hose 70 with a hydro-carbon gas supply. In the side of the chamber A is an opening 3 through which the pipe 7c may be swung on its pivot at s in the horizontal plane out of and into the chamber, to the center of the latter. Extending across the ring it is a bar n affording at its center a bearing n for a vertical shaft 2'. The shaft 'Z extends through an opening in the base Z of the chamberZ to a bearing, at its upper end, in a cross-bar Z at the top of the chamber Z. On the shaftz' in the chamber m is a turbine wheel 'Z', and in the chamber Z the shaft "Z carries a fanwheel 4?. Near the top of the basin 0 is an overflow opening 0', communicating with a spout 0 On one side of the drum A below the spout 0 is a feed water chamber h; and at the outer side of the upper end-portion of the chamber his a chamber h having an outlet spout h In the side of the receptacle B is a port g extending to the chamber h. Pivoted to a lug g in the receptacle B is a bellcrank lever g carrying at one end a float g and at its opposite end affording a valve 9 to open and close the port g.

In operation water under pressure enters at the pipe m which is contracted at its end, as shown, to reduce the incoming stream of water and increase its force. The water plays against the blades of the turbine wheel 11' causing the latter to rotate and turn the fan i Gas is turned into the hose 70 and filling the chamber Z0 it escapes through the openings k and rises around the nozzle 10 where it is ignited. The rotating fan 2' sucks air into the chamber Zthrough the opening Z and discharges it through the pipe 10,70 and nozzle 70 The nozzle Z0 with the adjacent parts of the pipe is aiford a gas burner, D. The force of the air from the nozzle creates a very hot flame at the burner, and forces it upward against the bottom of the receptacle, B, whence the hot products of combustion. rise around the receptacle to the outlets s. The

water after striking the turbine wheel falls into the ring n and escapes through the openings n to the basin 0. When the water in the basin rises to the outlet 0' it escapes through the spout 0 The'lower end of the spout 0 opens into the chambers h, h, so that part of the water flowing from that spout will enter the chamber h, and the balance will enter the chamber h and escape at the spout h The chamber h is heated by contact with the side of the drum A, so that the water in the chamber h will become heated. When the chamber h is filled with water to the port g, the water will run into the receptacle B, until the rise of the float g closes the valve 9 The limited quantity of water thus admitted to the receptacle Bis soon raised to the boiling point by the heat from the burner D, and the vapor rises through the opening 19 to the chamber 19. The chamber (1 is filled with asbestus or other non-heat conducting material q, to shield the chamberp from the heat of the receptacle B. The water in the basin 0 overlying the top of the chamber 19, tends to maintain the latter cool, so that vapor rising through the opening 19' is quickly condensed in the chamber 10, whence it escapes at a pipe p to a suitable receptacle not shown for storing the distilled water.

As stated the device shown is intended more especially for laboratory use. When it is not desired to employ the device for distilling water, the pipe 70' may be swung out of the chamber A, and the burner used for furnishing heat for other purposes. The heat from the burner is rendered very intense by the action of the blower, so that when the burner is swung out of the chamber A and the water is turned on to rotate the turbine wheel, the burner may be employed in melting metals or for other laboratory work where great heat is required.

What I claim as new, and desire to secure by Letters Patent, is

1. A water distilling device comprising 1n combination a vessel to receive the water to be heated, having a cover provided w th a downwardly inclined passage constituting a condensing chamber, said cover provldedon its upper side with a cold water receiving basin, a drum supporting the water heater, a burner furnishing heat to vaporize the water, an overflow pipe communicating with the basin, a feed water heating receptacle recelving its supply from the overflow, a port attording communication between the feed water heater and the water heating vessel, and a valve for opening and closing said port, controlled by a float, substantially as described.

-2. In a water distilling apparatus, the combination of a water heating vessel, a burner below the vessel, a condensing chamber coinmunicating with the vessel, a cold water receptacle adjacent to the condensing chamber, a water-pipe communicating with a cold water supply and conveying water to said cold water receptacle, a water supply conduit extending from the cold water receptacle to the said vessel, and means for supplying air under pressure to the burner, in the line of motion of the water from the said water-pipe, and actuated by the moving water, substantially as and for the purpose set forth.
